[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as those commonly understood by technicians in the technical field of this application; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship.

[0033] Reference to "embodiment" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0034] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects before and after are in an "or" relationship.

[0035] In the embodiments of the present application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary descriptions and should not constitute any limitation to the present application.

[0036] The term “plurality” used in this application refers to two or more (including two).

[0037] When a workpiece is bent, the workpiece can be placed in a fixed position and the part to be folded can be folded by a folding mechanism to achieve the bending of the workpiece. However, when a workpiece is bent, in addition to considering the bending forming effect of the workpiece, the bending efficiency of the workpiece is also an issue that cannot be ignored.

[0038] Taking the workpiece as a battery cell as an example, the battery cell includes a shell, an electrode assembly and an electrode terminal; the shell includes a shell and an end cover, the shell has an opening, the end cover covers the opening, and the electrode terminal is arranged on the end cover; the electrode assembly is accommodated in the shell, the electrode assembly has a pole ear, and the pole ear is connected to the electrode terminal. Before the end cover and the shell are covered, the pole ear needs to be accommodated in the shell together, so it is necessary to cover the shell and the end cover after the pole ear is bent. After the electrode assembly is accommodated in the shell, the battery cell can be placed in a fixed position, and then the pole ear is bent at the fixed position, and finally the processed battery cell is moved away from the fixed position to realize the bending processing step of the pole ear. In such a processing method, the production time of each battery cell is independent of each other, and the production time of each battery cell is composed of three steps: loading, processing and unloading. The processing of the battery cell takes a long time, which affects the production and processing efficiency of the battery cell.

[0039] In view of this, an embodiment of the present application provides a bending device, including a carrying mechanism, a driving mechanism and a folding mechanism. The carrying mechanism includes a plurality of positioning components, the plurality of positioning components are arranged along a first direction, the positioning components are used to position a workpiece, and the workpiece includes a portion to be folded; the driving mechanism is connected to the carrying mechanism, and the driving mechanism is configured to drive the carrying mechanism to move back and forth along the first direction to selectively switch the plurality of positioning components to a station to be folded; the folding mechanism is used to fold the portion to be folded of the workpiece on the positioning component at the station to be folded.

[0040] In such a bending device, by arranging a plurality of positioning assemblies along a first direction, the plurality of positioning assemblies can respectively locate the positions of a plurality of workpieces. By arranging a driving mechanism, the driving mechanism can drive the supporting mechanism to move along the first direction to adjust the positions of the plurality of positioning assemblies along the first direction. By arranging a folding mechanism, the folding mechanism can selectively bend the to-be-folded portions of the workpieces on the positioning assemblies. When the folding mechanism selectively folds the to-be-folded portions of the workpieces on the positioning assemblies, the remaining positioning assemblies are not at the to-be-folded stations, and the workpieces on the positioning assemblies that are not at the to-be-folded stations can be replaced. In this way, the time required for bending the workpieces is the time required for transferring different positioning assemblies to the to-be-folded stations and for bending the workpieces on the station assemblies at the to-be-folded stations, which saves the time consumed in replacing the workpieces and improves the production efficiency of the bending process of the workpieces.

[0041] The bending device is described in detail below with reference to the accompanying drawings.

The driving mechanism 20 is connected to the carrying mechanism 10, and the driving mechanism 20 is configured to drive the carrying mechanism 10 to move back and forth along the first direction X, so as to selectively switch the plurality of positioning components 1 to a station to be folded. The folding mechanism 30 is arranged along the second direction Y with the carrying mechanism 10, and the folding mechanism 30 is used to fold the portion to be folded of the workpiece 200 on the positioning components 1 at the station to be folded.

[0043] The supporting mechanism 10 is a component for supporting and positioning the workpiece 200. The supporting mechanism 10 may be one or more. The supporting mechanism 10 may have two, three, four, etc. positioning components 1. The multiple positioning components 1 are arranged along the first direction X. Along the first direction X, two adjacent positioning components 1 may be connected, for example, two adjacent positioning components 1 abut against each other; or two adjacent positioning components 1 may be arranged at intervals. Each positioning component 1 can position a workpiece 200 individually. The positioning component 1 may be provided with a clamping portion, and the workpiece 200 may be clamped by the clamping portion; or the positioning component 1 may be provided with a groove, and a part of the workpiece 200 is accommodated in the groove to locate the position of the workpiece 200. In the embodiment where the supporting mechanism 10 is multiple, the folding mechanism 30 may also be multiple, and the folding mechanism 30 corresponds to the supporting mechanism 10 one by one.

[0044] The driving mechanism 20 can drive the carrying mechanism 10 to move back and forth along the first direction X, that is, the driving mechanism 20 can drive the multiple positioning components 1 to move synchronously along the first direction X. In the process of the driving mechanism 20 driving the carrying mechanism 10 to move back and forth along the first direction X, one of the multiple positioning components 1 will move out of the to-be-folded station, and at the same time, one of the multiple positioning components 1 that is not in the to-be-folded station will move to the to-be-folded station.

[0045] For example, the driving mechanism 20 may include a first driving part 201 and a first executing part 202, wherein the first driving part 201 is connected to the first executing part 202, and the first driving part 201 is configured to drive the first executing part 202 to move along the first direction X; multiple positioning components 1 are connected to the first executing part 202, and the first executing part 202 can drive multiple positioning components 1 to move synchronously along the first direction X. The first driving part 201 may be a screw nut structure, and the first executing part 202 may be a bearing plate, and multiple positioning components 1 are arranged on the bearing plate, and the screw nut structure drives the bearing plate to move along the first direction X.

[0046] The positioning assembly 1 may be fixedly connected to the driving mechanism 20, and after the driving mechanism 20 selectively moves the multiple positioning assemblies 1 to the folding station, the folding mechanism 30 performs bending processing on the workpiece 200 on the positioning assembly 1 positioned at the folding station. The positioning assembly 1 may also be movably connected to the driving mechanism 20, and after the driving mechanism 20 selectively moves the multiple positioning assemblies 1 to the folding station, the positioning assembly 1 may be adjusted to a fixed position at the folding station to facilitate the folding mechanism 30 to bend the workpiece 200; wherein the positioning assembly 1 may move along the second direction Y or along the third direction Z, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0047] The folding mechanism 30 is used to fold the to-be-folded portion of the workpiece 200 located on the positioning assembly 1 at the to-be-folded station. The folding mechanism 30 and the carrying mechanism 10 may be arranged along the second direction Y, and the carrying mechanism 10 moves along the first direction X so that the plurality of positioning assemblies 1 selectively approach the folding mechanism 30 to achieve the folding of the workpiece 200; or the folding mechanism 30 and the carrying mechanism 10 may be arranged along the first direction X, and the positioning assemblies 1 are provided on both sides of the folding mechanism 30 along the first direction X, and the carrying mechanism 10 moves along the first direction X so that the plurality of positioning assemblies 1 selectively approach the folding mechanism 30 to achieve the folding of the workpiece 200.

[0048] The folding mechanism 30 and the carrying mechanism 10 are arranged along the second direction Y, and the first driving unit 2 can drive the positioning assembly 1 to move along the second direction Y, so that the positioning assembly 1 can be close to or away from the folding mechanism 30. The positioning assembly 1 may have two positions at the to-be-folded station, and the first driving unit 2 can drive the positioning assembly 1 to switch between the two positions; wherein, along the second direction Y, one of the two positions is arranged close to the folding mechanism 30, and the other is arranged away from the folding mechanism 30, when the positioning assembly 1 is located at a position close to the folding mechanism 30, the folding mechanism 30 can fold the to-be-folded portion of the workpiece 200 at this position, and when the positioning assembly 1 is located at a position away from the folding mechanism 30, the driving mechanism 20 can drive the carrying mechanism 10 to move along the first direction X. Each first driving unit 2 is connected to a positioning assembly 1, and each first driving unit 2 can drive a positioning assembly 1 to move along the first direction X alone.

[0049] The first driving unit 2 may include a first motor 21 and a first guide rail 22 . The positioning assembly 1 is disposed on the first guide rail 22 . The first motor 21 may drive the positioning assembly 1 to move along the second direction Y on the first guide rail 22 .

[0050] In the embodiment of the present application, by setting a plurality of positioning assemblies 1 along the first direction X, the plurality of positioning assemblies 1 can respectively locate the positions of a plurality of workpieces 200. By setting a driving mechanism 20, the driving mechanism 20 can drive the carrying mechanism 10 to move along the first direction X to adjust the positions of the plurality of positioning assemblies 1 along the first direction X. By setting a first driving unit 2 to drive the positioning assembly 1 to move back and forth along the second direction Y, the first driving unit 2 can change the position of the positioning assembly 1, so that the workpiece 200 on the positioning assembly 1 can be close to or away from the folding mechanism 30, so that the bending device 100 can process the workpiece 200 when the positioning assembly 1 is close to the folding mechanism 30, and replace the workpiece 200 when the positioning assembly 1 is away from the folding mechanism 30, thereby reducing the risk of interference between the positioning assembly 1 and the folding mechanism 30 when replacing the workpiece 200. By setting the folding mechanism 30, the folding mechanism 30 can selectively bend the part to be folded of the workpiece 200 on the positioning assembly 1. When the folding mechanism 30 selectively folds the part to be folded of the workpiece 200 on the positioning component 1, the remaining positioning components 1 are not in the folding station, and the workpiece 200 on the positioning component 1 that is not in the folding station can be replaced. In this way, the time required for bending the workpiece 200 is the time for transferring different positioning components 1 to the folding station and bending the workpiece 200 on the station component of the folding station, which saves the time spent on replacing the workpiece 200 and improves the production efficiency of the bending processing of the workpiece 200.

[0051] In some embodiments, please refer to Figure 3The positioning assembly 1 includes a placement platform 11 and a support member 12; the placement platform 11 is used to carry the workpiece 200; the support member 12 is arranged on the placement platform 11, along the second direction Y, the support member 12 is arranged on the side of the placement platform 11 away from the folding mechanism 30, and the support member 12 is used to abut the workpiece 200 to limit the workpiece 200 from moving in the direction away from the folding mechanism 30.

[0052] The placement platform 11 is used to carry the workpiece 200 to provide stable support for the workpiece 200. The first driving unit 2 can drive the placement platform 11 to move along the second direction Y, so that the workpiece 200 on the placement platform 11 moves along the second direction Y.

[0053] The abutment member 12 is arranged on the placement platform 11, and the abutment member 12 can move synchronously with the placement platform 11, so that the abutment member 12 can keep abutting against the workpiece 200 on the placement platform 11 when the placement platform 11 moves. The workpiece 200 has a first end where the part to be folded is arranged and a second end that cooperates with the abutment member 12, and the first end and the second end are arranged relatively along the second direction Y, and the abutment member 12 abuts against the second end to lower the workpiece 200 from the placement platform 11 in the direction from the first end to the second end. The abutment member 12 can be fixedly connected to the placement platform 11; or the abutment member 12 can be movably connected to the placement platform 11, for example, the abutment member 12 can move along the second direction Y relative to the placement platform 11.

[0054] By arranging the abutment member 12 on the side of the placement platform 11 away from the folding mechanism 30, the abutment member 12 can limit the workpiece 200 on the placement platform 11 from moving in the direction away from the folding mechanism 30, thereby making the position of the workpiece 200 more stable and improving the stability of the folding mechanism 30 when folding the workpiece 200.

[0055] In some embodiments, please refer to Figure 3 The positioning assembly 1 further includes a first adjusting unit 13 , which is connected to the abutting member 12 and the placement platform 11 , and is configured to adjust the position of the abutting member 12 along the second direction Y.

The first telescopic member may be a pneumatic telescopic rod.

[0057] By adjusting the position of the abutment member 12 along the second direction Y through the first adjustment unit 13, the abutment member 12 can be abutted against the workpiece 200 at different positions, thereby adjusting the relative position of the workpiece 200 and the placement platform 11 along the second direction Y, which is beneficial for the positioning component 1 to position workpieces 200 of different models and improve the practicality of the bending device 100.

[0058] In some embodiments, please refer to Figure 3 The positioning assembly 1 further includes a clamping unit 14 , which is disposed on the placement platform 11 , and is used to clamp the workpiece 200 along the first direction X.

[0059] The clamping unit 14 clamps the two sides of the workpiece 200 along the first direction X to limit the position of the workpiece 200 along the first direction X. The clamping unit 14 clamps the workpiece 200 to fix the position of the workpiece 200 .

[0060] The clamping unit 14 may include a first clamping portion 141 and a second clamping portion 142, which are relatively arranged on both sides of the placement platform 11 along the first direction X. The first clamping portion 141 and the second clamping portion 142 move toward each other along the first direction X to clamp the workpiece 200.

[0068] In some embodiments, please refer to Figure 6 , Figure 6 for Figure 2 A partial enlarged view of the area A in the middle. The workpiece 200 also includes a first part and a second part, the part to be folded connects the first part and the second part, and the positioning assembly 1 is used to position the first part of the workpiece 200; the folding mechanism 30 and the supporting mechanism 10 are arranged along the second direction Y, and the folding mechanism 30 includes a folding knife assembly 301 and a flipping assembly 302; the folding knife assembly 301 includes a first folding knife 3011, a second folding knife 3012, and a second adjusting unit 3013, the first folding knife 3011 and the second folding knife 3012 are arranged relatively along the third direction Z, and the second adjusting unit 3013 is used to adjust the distance between the first folding knife 3011 and the second folding knife 3012, the first folding knife 3011 and the second folding knife 3012 are used to cooperate to clamp the part to be folded, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other; the flipping assembly 302 is used to drive the second part to flip around the axis extending along the first direction X.

[0072] By setting the folding knife assembly 301 to cooperate with clamping the part to be folded, the folding knife assembly 301 can limit the position of the part to be folded; by setting the flipping assembly 302 to drive the second part to flip around the axis extending along the first direction X, the flipping assembly 302 cooperates with the folding knife assembly 301 to bend a crease in the part to be folded, thereby realizing the bending of the part to be folded.

[0073] In some embodiments, please refer to Figure 6The flip assembly 302 includes a clamping unit 3021, a flip unit 3022, and a second driving unit 3023; the clamping unit 3021 is used to clamp the second part; the flip unit 3022 is connected to the clamping unit 3021, and the flip unit 3022 is configured to drive the clamping unit 3021 to rotate around an axis extending along the first direction X; the second driving unit 3023 is connected to the flip unit 3022, and the second driving unit 3023 is configured to drive the flip unit 3022 to move along the second direction Y and the third direction Z.

The flip unit 3022 may be a motor, and the rotation axis of the motor extends along the first direction X.

[0076] The second driving unit 3023 can drive the flip unit 3022 to move along the second direction Y and the third direction Z. The second driving unit 3023 may include a second motor 30231, a second guide rail 30232, a third motor 30233, and a third guide rail 30234. The third guide rail 30234 is located on the second guide rail 30232, the second motor 30231 connects the second guide rail 30232 and the third guide rail 30234, and the second motor 30231 can drive the third guide rail 30234 to move along the second direction Y on the second guide rail 30232.

[0078] In some embodiments, please refer to Figure 7 , Figure 7A schematic diagram of the structure of a folding knife assembly 301 provided in some embodiments of the present application. The second adjustment unit 3013 includes a first driving member 30131 and a second driving member 30132; the first driving member 30131 is connected to the first folding knife 3011, and the first driving member 30131 is configured to drive the first folding knife 3011 to move along a first preset direction; the second driving member 30132 is connected to the second folding knife 3012, and the second driving member 30132 is configured to drive the second folding knife 3012 to move along a second preset direction; wherein at least one of the first preset direction and the second preset direction is arranged at an angle with the third direction Z, and the angle is an acute angle.

[0079] The first folding knife 3011 can move under the drive of the first driving member 30131, and the second folding knife 3012 can move under the drive of the second driving member 30132. The movements of the first folding knife 3011 and the second folding knife 3012 are independent of each other.

[0080] The first driving member 30131 and the second driving member 30132 may both be telescopic members, which control the extension or retraction of the first folding knife 3011 or the second folding knife 3012 to move the first folding knife 3011 and the second folding knife 3012 closer to or farther from each other.

The third direction Z may be a height direction, and the first folding knife 3011 may be located above the second folding knife 3012. After the first folding knife 3011 and the second folding knife 3012 cooperate to clamp the part to be folded and the flipping assembly 302 drives the second part to flip upward, a first crease will be formed on the part to be folded; then the first folding knife 3011 retracts, and the second folding knife 3012 can continue to extend, so that the second folding knife 3012 pushes out of the part to be folded between the first part and the first crease, and the first crease is located between the second folding knife 3012 and the clamping unit 3021, and the clamping unit 3021 is driven by the second driving unit 3023 to lean against the second folding knife 3012, so that the second folding knife 3012 and the clamping unit 3021 cooperate to clamp the part to be folded, so as to realize the secondary bending of the part to be folded.

One carrier 10 corresponds to one folding mechanism 30, and each carrier 10 corresponds to one station to be folded. The multiple positioning components 1 of each carrier 10 selectively switch to its own station to be folded, so that the folding mechanism 30 folds the part to be folded of the workpiece 200 located on the positioning component 1 of the station to be folded. In this way, one folding mechanism 30 can fold one workpiece 200, and the bending device 100 can perform bending processing on multiple workpieces 200 at the same time.

[0086] In this embodiment, the plurality of carrying mechanisms 10 can carry more workpieces 200 , and the plurality of folding mechanisms 30 can fold more workpieces 200 simultaneously, thereby improving the bending efficiency of the bending device 100 .

[0087] Please continue to refer to Figure 8The embodiment of the present application provides a bending device 100, comprising a plurality of carrying mechanisms 10, a driving mechanism 20 and a plurality of folding mechanisms 30. The plurality of carrying mechanisms 10 are arranged along a first direction X, and each carrying mechanism 10 corresponds to a station to be folded. The driving mechanism 20 is connected to the plurality of carrying mechanisms 10, and the driving mechanism 20 is configured to drive the plurality of carrying mechanisms 10 to move synchronously along the first direction X; the folding mechanism 30 corresponds to the carrying mechanism 10 one by one. The carrying mechanism 10 comprises a plurality of positioning components 1, and the plurality of positioning components 1 are arranged along the first direction X, and the positioning components 1 are used to position a workpiece 200, and the workpiece 200 comprises a portion to be folded. The carrying mechanism 10 further comprises a plurality of first driving units 2, and the first driving units 2 correspond to the positioning components 1 one by one, and the first driving units 2 are configured to drive the positioning components 1 to move back and forth along the second direction Y. The driving mechanism 20 is connected to the carrying mechanism 10, and the driving mechanism 20 is configured to drive the carrying mechanism 10 to move back and forth along the first direction X, so as to selectively switch the plurality of positioning components 1 to the station to be folded. The folding mechanism 30 includes a folding knife assembly 301 and a flipping assembly 302; the folding knife assembly 301 includes a first folding knife 3011, a second folding knife 3012 and a second adjusting unit 3013, the first folding knife 3011 and the second folding knife 3012 are arranged relatively to each other along a third direction Z, the second adjusting unit 3013 is used to adjust the distance between the first folding knife 3011 and the second folding knife 3012, and the first folding knife 3011 and the second folding knife 3012 are used to cooperate in clamping the part to be folded. The flipping assembly 302 includes a clamping unit 3021, a flipping unit 3022 and a second driving unit 3023; the clamping unit 3021 is used to clamp the second part; the flipping unit 3022 is connected to the clamping unit 3021, and the flipping unit 3022 is configured to drive the clamping unit 3021 to rotate around an axis extending along the first direction X; the second driving unit 3023 is connected to the flipping unit 3022, and the second driving unit 3023 is configured to drive the flipping unit 3022 to move along the second direction Y and the third direction Z.

[0088] In this embodiment, by arranging a plurality of positioning assemblies 1 along the first direction X, the plurality of positioning assemblies 1 can respectively locate the positions of the plurality of workpieces 200. By arranging the driving mechanism 20, the driving mechanism 20 can drive the carrying mechanism 10 to move along the first direction X to adjust the positions of the plurality of positioning assemblies 1 along the first direction X. By arranging the folding mechanism 30, the folding mechanism 30 can selectively bend the to-be-folded portions of the workpiece 200 on the positioning assembly 1. When the folding mechanism 30 selectively folds the to-be-folded portions of the workpiece 200 on the positioning assembly 1, the remaining positioning assemblies 1 are not in the to-be-folded stations, and the workpiece 200 on the positioning assemblies 1 that are not in the to-be-folded stations can be replaced. In this way, the time required for bending the workpiece 200 is the time required for transferring different positioning assemblies 1 to the to-be-folded stations and bending the workpiece 200 on the station assembly of the to-be-folded station, which saves the time consumed in replacing the workpiece 200 and improves the production efficiency of the bending process of the workpiece 200.
